SPEC CPU2017 Platform Settings for ASUSTek Systems

Patrol scrubbing is a mechanism for the memory controller to periodically read all memory locations and write back corrected data.
The time interval for scrubbing the entire memory is defaulted to 24-hour period.

Sub NUMA Clustering (SNC) is a feature for breaking up the LLC into disjoint clusters based on address range, with each cluster bound to a subset of the memory controllers in the system.
It improves average latency to the LLC and is an important pre-requisite to enabling KTI prefetch and is a replacement for the Cluster-on-Die feature found in previous processors.

IMC Interleaving:

This BIOS option controls the interleaving between the Integrated Memory Controllers (IMCs).
If IMC Interleaving is set to two-way, the memory addresses will be interleaved between the two IMCs.
If IMC Interleaving is set to one-way, there will be no interleaving. If SNC is enabled, you want one -way interleave.
If SNC is disabled, you want two -way interleave. (See also Sub-NUMA Cluster.) Values for this BIOS option can be:

One-way: no interleaving

Two-way: interleaving

SR-IOV Support:

In virtualization, single root input/output virtualization or SR-IOV is a specification that allows the isolation of the PCI Express resources for manageability and performance reasons.
A single physical PCI Express can be shared on a virtual environment using the SR-IOV specification.
If system has SR-IOV capable PCIe Devices, this option Enables or Disables Single Root IO Virtualization Support.

ENERGY_PERF_BIAS_CFG mode:

This BIOS option allows for processor performance and power optmization. Available settings are:
